What to include
For a correction, include the page URL, the passage concerned and a reliable source supporting the proposed change. If the issue depends on a software version, identify that version and explain where the behavior differs.
For a tool problem, describe the steps that led to it, the displayed error and your browser or device where relevant. Share a public test URL only if it is safe to disclose. Do not send passwords, access tokens, private customer data or authenticated links.
What this mailbox covers
You can contact WebVitalsDev about editorial questions, corrections, tool behavior, accessibility barriers and advertising or sponsorship inquiries. For an accessibility issue, describe the page, the action you were trying to complete and any assistive technology relevant to the problem.
There is no contact form, telephone contact or published office address. Email is the contact route. WebVitalsDev does not promise a particular response time or provide an emergency support service.
Before sending an advertising inquiry
Read the advertising page for the formats and editorial boundaries. Include the proposed subject, placement and commercial relationship so the inquiry can be assessed clearly.
For content changes, the corrections policy explains how material errors are handled. Sending a request does not guarantee publication or a change to an article's conclusions.
